t BEARING.

Application filed December 10, 1923.

My invention relates to liearings and, more particularly, to :infljustsible bases 'or bearings which provide great 'flexibility in installation and adjustment.

My :invention has lo do with bearin s which are adapted to be carried upon suitable supports and are :uljustable thereon. One oft thermain objects oi" my invention is to provide :i bearing wherein maximum ease and simplicity in installation is provided. and wherein a wide range olf adjustment with rel'ereucc lo its support nuiy be accom plished.

Another object ot my invention is io provide a, bearing which may i i attached to its support without the lrilling` oi holesI in the supj'iort, or otherwise distorting or niarring the support, whereby the maximlnn strength olf' the support is maintained. This "Feature eliminatesI aligning et holes .in the bearing base with holes in the bearing sujiport.

There may be instances when it is neces sary tor the .tacos o'lf the opposed bearings to remain in a lixod or constant distance apart regardless oi the varying oi' the distance between the bearing supports. An-v other object ot my invention to provide for this feature. In other words, the use ot my invention enables the spacing between the bearing' supports to be varied, while nniintaining the spacing between the tacos ol' the bearings constant; or my invention permits the spacing between the laces ot the opposed bearings to be varied or to remain constant iinflepemlently olf' spacing between the respective bearing supports.

There may also be instances `where the supporting su ritace ot the bealving supports varies in width, and still another object oit my invention is to provide means .tor attacliingl the bearing base to its support regardles` vo'lf the width ot the bea-rim; base support. lhiii may be done without the drilling oi any holesl or iu any Wayinarring, d tortingg; or weakening the bearing support. .A lfurthcr object o'l' my invention is to provide means whereby the bearing may be set upon its support at any angle with respect to the longitudinal. axis o t its respective supn port. In other words, my invention provides for the placing ol'v the shait, carried by the bearing, :it any position along the longitudinal. axes oi the bearing supports. In

Serial N. 679,612.

this respect, my invention provides means whereby the bearings can be adjusted to any position and at any angle with respect to the longitudinal axes of' the bearing supports without the necessity ot punching holes in the supports, thereby providing a bearing readily' accessible and easy to adjust, at the same time eliminating the necessity oi making a varying number of holes in the bearing support in order to apply the bearing to the variable positions above referred to.

Other objects and advantages oi my in* vention will become apparent by reference to the speeiiication Yfollowing hereafter and by inspection oit the drawings anni-med hereto.

My invention may be applied to any bearing which is carried. upon a separate 'supporting means. However, in order to i'ully explain and describe my invention, @l have chosen a form ot' structure as applied to bearings tor carrying a pulley, such as that known as the crown pulley in drilling rig structures. Y

The iorm ot' structure which I have chosen to illust 1ate my invention is shown in the accompanying drawings, wherein,

Figure l is a side view, partly in section, ot a structure employing my invention. This View illustrates a part of the internal portion of the bearing showing` the relative position olf its parts and the .lubricating means cooperating with such operating parts.

Figure 2 is an end View olA the bearing with a. portion of the looltingl flange boss shown in section.

Figure 3 shows my invention employed in securing the bearings to I-beam supporting members.

Figure 4t is a plan view oif the structure shown in Figure 3, illustrating the bearings arranged in parallelism with the bearing supports.

Figure 5 is a ragmental view ot a struc ture employing my invention and illustrating the application of the bearing employ .ing my invention to bearfngsupports ot varying supporting widths. The dotted and full lines illustrate supporting members oit' varying sizes.

Figure 6 is a View oi a portion ot the structure similar to that shown in Figure 5 il (l but illustratingr the manner in which the spacing between the support-ing members may be varied without vaiying the spacing between the adjacent faces of the bearings.

Figure 7 is a plan view of a structure similar to that; shown in Figure/ t but; illus-4 trating the manner in which the bearings, or either of them, may be set at. yar angles with respect to the longitudinal of the respective supporting member. Y

Figure 8 is a view taken on line BWI?) of Figure l. y

In the drawings, my invention is shown as comprising abearing base i, with a lining as at 2, and having the edges of the said lining beveled as at 3 to' aid in keeping a supply of oil on the shaft adapted to bnr and be supported upon the lining 2, assisting in lubrication' thereof. rIhe bearing base l is provided with upstanding ledges at paralleling the shaft bearing, such ledges et being adapted to eo-act with depending ledges 5 of the bearing cap 6, the entire bearing as a unit being held in parallel relation'to the shaft to be carried thereby. In the structure shown, the shaft to be used requires a bearing surface only in its ,lower side since all of its forces are in a downward direction. rIlhe bearing cap is provided with an outer Vall T and an inner wall S, as shown in Figure l, of the dra-wing to form a lubricant reservoir 3l). The inner wall 8 is'arranged concentrically with relation to the shaft and is spaced an appreciable distance from the shaft. The upper edges of this inner wall S are broken so as to form an open space 9' at the top. the opening being formed by the flanges 10 of the innerauil-l as shown in Figure l. opening 9 leads from the lubricant reservoir 3()7 to the shaft carried by the lining rIlhe upper portion of the outer wall 'terminates in an opening which is covered by the lid' ll. The reser'i'f'oir El() is adapted to carry a lubricant and the opening covered by the lid ll is provided for the purpose of supplying the lubricant t'o the said reservoir and'for cleaning`- out same and the like.

Referring particularly to Figures l and S. in order to feedy ,the lubricant from the reservoir to the shaft7A I provide means cour prising a felt pad l2 which is carried bv and secured to a clip member 13, preferably. by riveting' the pad' thereto. This clip member 13 is so shaped that it will snap or hook over the iuiistandingflanges l0 of the inner wall and remains in place without the possibility of the felt padv l2 being displaced', curledI or wrinkled. As shown in F igjure 8. a wick member 14 or plurality of wick members, as desired, is secured to the feltl pad l2, preferably, by riveting; The wiel( member 14 is of such" lei'igtlrthat it will extend up over the upstanding parallel flanges 10' and downv into tlie lubricant in the luhri :ant reservoir ltl. The telt, pad lf2, preferably, is of such thickness and so located that it will contact willi the sha l't to be. carried by the lining i2.

lith this constriu-tiom duc to capillam attraction. the lul'nicant in the cavity br tween the walls T and S is carried through the wich or wirlis l-l; to tlu` felt pad li. This lubricant is carried to thc telt pad tt. until a state of saturation elleclwl, 'l`huu it is obviousl that the lubricant is automati cally supplied to the. shaft and its bearing at only those times when required: because. when the shaftl is rotating and the maximum amount of lubricant is required. thc lsha t'l is constantly carrying the lubricant away l'rom the felt pad l2 and when the lshaft is stopped and the point ol' saturation ol pad l2 is reached, the feeding oi the lubricam ceases. This construction eliminates waste of the lubricant.

In the oiling construction above described. there may be instances where larger or smaller bearings may be used or where. due to the nature of the work reipiired. a greater amountoi lubricant is ,ncccssizcn lu my structure. I have provided means l'or taltinsxi care of any such varying` conditions by the arrangenient of the parts shown, whereby il will be seen that thc amount aml raie oll supply ot lubrilant to the pad member l' directly dependent upon the size and the nature ot the wick or wicks lil: that if-z to say. larger or smaller wicks may be used. and the quality of the wiel; changed. as the circumstances require. Although .l employ a felt pad l2. it is to be understood that thc pad l2 may be of any suitabl and desired material.

The oiling means` de:-:cribcd above. is casi` ly accessible, is simple in construction und easy to manipulate and greatly l'acilit: les installation and repairs. 'thisl is better emphasized by the fact that the oiiing wichsand pad are removable as a uni? bv merely opening lid ll and removing` the clips ll. Another very great advantage lies4 in Athc fact that foreign particles in thc oil do not readily clog or retard the oil liow. ThisA perniits of the use ot low grades of oil o'.- salvageil oil containing sediment' etc. 'l`he above means which ,l provide for oiling tlu` bearing is very economical in that it redme:`l the amount of lubricant used to only that amount required under the circumstances and feeds the lubricant onij.v at the time rcquired and needed.

The bearing base l is entende-i horizontally at the bottom` as at la. and is provided with openii'igs 'iti having counteresunlt portions 17. The bearing rap is also provided with horizontall)V extending ings lll which are provided with openings itl adapted to align with openings iti in the bearing base. The bearing base l and cap G are heldy rigid-V Htl fili

lltl

ly together in longitudinal alignment by bolts 2() which are passed through the openings 1.6 and 19 in the base and cap respcetively, the bolts being tigl'item-d up and held in place by the nuts ill.

In the structure that l have chosen to illustrate my invent-ion. I employ I-beanis .42 (Figs. tl and 7 inclusive) which serve as hearing supports, the upper Hanging portion 23 of the beam being employed as the bearing base supporting surface. In the drawings, I have shown two bearings arranged in parallelism and carrying a shaft which in turn carries the pulley 24. This pulley 24. may be put to various uses, an example of it would be a crown pulley as used in a drilling rig structure.

It is well known that bearings, ol the type shown, may be used under varying conditions in the same installation or one certain bearing or set of bearings may be used in different installations wherein the size, shape or alignment of thesupportinfr surface may vary. For example, the bearing may be applied to a wider or narrower supporting Surface of the same or different shape or the bearing may be moved longitudinally of the suport or moved laterally ot the support, or tie support may be moved closer together or farther apart or the bearing may be adjusted with an angular relation to the longitudinal axis of the support. lVith the use of the ordinary bearing structures, such asthose that are removably carried upon a support, the above conditions require the drllling of new holes in the support or supports, or the supporting surfaces must originally be provided with a varying number and series of openings for the insertion of bolts or the like for securing the bearing base to its support to provide for such conditions to insure interchangeability. Also, such an arrangement as this requires that both the bearing and the bearing support be disturbed and alignment effected, eaus ing considerable trouble and ditliculty in installation or repair work and resulting many times in improper alignment of the bearing parts Which cause excessive wear et cetera. In my invention I overcome the difficulty encountered in the above circumstances by employing a bearing structure which is adapted tobe adjusted to any position relative to its support or which permits the sup port to be adjusted to anyposition without disturbing the fixed position of the bearing. In other words, my invention provides for the adjustment of the bearing upon its support to any predetermined and desired position or permits the adjustment of the bearing support to any position without disturbing and removing or distiguring either the bearing itselt or the bearing support. The means which I have provided for carrying out my invention may comprise the angu- Vbosses 25 and 2G and holes 27 as shown in Figs. l and a. Each of the holes 27 is adapted to receive a suitably shaped clamp bolt Q8 which bent or formed at one end to hook over or otherwise engage the bearing supporting surface suoli as the I-beam flanges 23 shown in the drawings. The opposite end of each clamp bolt is threaded to receive an adjusting nut Q9. In assembling each clamp bolt 28 is thrust through the hole 27 in its respective boss so that the hook or support engaging end hooks over or otherwise engages the bearing supporting surface. Each nut 29 is then applied and tightened up to suit the desired adj ustment. lVith all of the clamp bolts 2S applied.` suitably adjusted, and tightened, the bearing, as an entirety, is held rigidly and securely upon its support.

It is desirable that the adjacent faces olf the opposite bearings, such as bearings A and B shown in Fig. 3, be held in apredetermined parallel alignment one witl'r respect to the other in order to provide the desired bearing surface without undue restriction and wear. In employing my iinvention, the adjacent faces of the opposite bearings can be positively adjusted so as to have an accurate parallel relation by merely adjusting and manipulating the clamp bolts 28 and their respective adjusting nuts 29. This can be readily etfected with my invention without removing the bearing base l from its support 23 and without in any way distorting the support 23. For example, when it is desired to install. the bearings A and B (Fig. 3) with. their :uljacent aces in parallel relation, the adjusting nuts 29 on the clamp bolts 25 and 2G are loosened and tightened respectively so as to swing the respective end ot the bearing in either direction as desired. This ai'ljustment can take place at either end ot the bearing as ocjasion requires.

Furthermore. my invention provides tor rea dy adjustment under circumstances where a certain bearing or set ot bearings being employed in a certa in installation on one set of supports and it becomes necessary to apply this same bearing or set ot bearings to another support in the same or ditlbrent installation. the supporting surface of the new support being wider or narrower. As

`shown in Fig. 5 oi the drawings, this condition is readily taken care ot by merely reapplying` the clamps 28 as previously described, the only difference being that the nuts 29 may be tightened up more or less on the respective clamp bolts to bring about the proper' adjustment and securemcnt oli the lgiearing to its support. ln applying the clamp boltsl 2S to wider or narrower supportN lng surfaces, the angle ol" the bolt changes to a degree dependent upon the change in width ot' the support. To take care ot this variation. l i'orm the clamp bolt holes QT vith an enlarged bottom portion. This enlarged portion ot the bolt holes 2T also compensates tor any other change in angularity ol the clamp bolts caused by moving the same.

Another advantage in the use ot my invention is in the case ot the use olf a pulley 24 as shown where a pulley shoulder to shoulder dimensions ot predetermined amount is employed and where it desirable that the bearing base give support to the pulley trunnion over its entire length; that is to say, where it is desirable to maintain the distance between the races of the bearings, the same as the distance between the faces oi the pulley hub structure. Although it is desirable to maintain this condition between the taces ot the bearings, it becomes desirable, at times, to change the spacing between the bearing supports. Bly invention meets the above conditions by providing means such as the adjustable clamp bolts 28, whereby the bearing supports may be moved closer together or farther apart without changing the predetermined fixed spacing between the adjacent bearing taces and without removing the bearings from their` supports or in any way distorting the bearing supports. This feature otl my invention is illustrated in Fig. 6 ot' the drawings. 'In Fig. 6, the solid lines show the bearings support, in its original position while the dotted lines show it in position atter the supports have been moved closer together. the spacing between the adjacent taces of the opposite bearings remaining constant. ln this instance the change is made by merely looseningthe nut 29 on the clamp bolt Q5 and tightening` the nut on the clamp bolt 2G after the support has been moved over. Vvlhen the supports are mov-ed turther apart, the manipulation and the adjusting of the clamp bolts 28 is just opposite to that above described, the ultimate effect being the same.

There will be instances when it is desired to adjust the bearings at an angle to the longitudinal axes of the supporting members instead ot parallel therewith. A n example of this is in the ease of the use of a pulley 24, as shown, where it is necessary to adjust the pulley at various angles to accommodate the angularity ot the cable or 4otherwise changing the support ilsell.

rope to be used over the pulley. l have demonstrated the application olI my invention to such a circumsllmcc in Fig. T o' the drawings. The result shown inlfig. T is obtained by loosening and tightening (he nuts 2li on the respective cla-iup boli:4 11.7 and 2G l'or bolli bcariiufs and ll lo the desired cxlcnl dcpcmlcnl upon the angle at which the bearing is lo be turned. ll'ilh my bearing (.:lamping arrangcnunl. bolli bearings may be readily turned al the dcsired angle, and quickly adjusted in parallelism without dilliculty und without removing the. bearings trom their supports or in any way di:-;torting the supports.

lt. will be umla'stood that while l have shown my'inventnm as applied lo an 'llbcam supporting structure and a pulley bearing structure.. l do not limit my invention io nuCll, since it may be applied lo vewious i nps porting structures ol' various shznlief'` and sizes by making a cm'vesponlling change in shape and size in the attaching portion ot the clamp bolts. this being done without. in any way, departing Irom the scope ol'V my invention.

From the Yforegoing description and by inspecting the drawings. it will be .seen that my invention provides a neat. compact. simple and exceedingly llexible adjuslablc bearing structure. wherein a wide range o E' adjnstii'ient with respect to this support muy be accomplished. It will also be seen llnu my invention provides a var 'ving adjustable bearing which may be applied lo ils support without the drilling ot holesy or in any other manner distorting the support. whereby the maximum strength ol the support at all times maintained. My structure. 'further-- more. simplifies installation and repair by elin'iinating the necessity ot drilling holcs and lining up the same.

Another advantage of my invention is the provision' for the changing ol' the position and spacing relation ot the bearing supports without changing the position and spacing relation between the adjacent laces o'l" the bearings. This is also accomplished without. in any way. distorting or mari-ing the supporting members.v Also. il will be seen that my invention provides for the use ot a certain bearing in varying installations regardless ot lhe width ol'Y the new .supportA ing members. ln other words. my invention reduces the cost ol' uplieep and installation by `lnfoviding 'for interchangeability. Still another and important feature olI my invention, as amplified by the foregoing description. is. that it enables the bearing to be readily adjusted upon its lsupport at any desired angle with respect to the longitudinal axis ot the support, this being); accomplished without removing the bearing from its support or distorting. marring. or lt lllll llll Il i) :is also obvious that .my invention provides for 'vertical adjustment of eaeh bearii'lg relative to its support.
